ROPgadget Tool
================

This tool lets you search your gadgets on your binaries to facilitate your ROP exploitation.
ROPgadget supports ELF/PE/Mach-O format on x86, x64, ARM, ARM64, PowerPC, SPARC and MIPS
architectures. Since the version 5, ROPgadget has a new core which is written in Python
using Capstone disassembly framework for the gadgets search engine - The older version can
be found in the Archives directory but it will not be maintained.

Install
-------

If you want to use ROPgadget, you have to install [Capstone](http://www.capstone-engine.org/) first.

For the Capstone's installation on nix machine:

    $ sudo pip install capstone

Capstone supports multi-platforms (windows, ios, android, cygwin...). For the cross-compilation,
please refer to the https://github.com/aquynh/capstone/blob/master/COMPILE.TXT file.

After Capstone is installed, ROPgadget can be used as a standalone tool:

    $ ROPgadget.py

Or installed into the Python site-packages library, and executed from $PATH.

    $ python setup.py install
    $ ROPgadget

Or installed from PyPi

    $ pip install ropgadget
    $ ROPgadget

How can I contribute ?
----------------------

- Use Z3 to solve the ROP chain
- Add system gadgets for PPC, Sparc, ARM64 (Gadgets.addSYSGadgets())
- Manage big endian in Mach-O format like the ELF classe.
- Everything you think is cool :)
